Yeah, in addition to making the tykes a dwarf variety and reskinning other enemies into different subspecies, I am making them inherently evil non-people. I think maybe it will be the "reward" for Auril cultists: get transformed into a horrible monster! I will intentionally blur the yeti and wendigo I think, too.That's kind of problematioc though... Yetis are a sapient species.
I like stock enemies but I like them more when they are, like Nazis and zombies, guilt free kills for the heroes.
Also if it isn't clear thus far, I am not really going to be leaning into the horror aspects of the game. The trappings, sure, but that's all D&D. But I won't be trying to make this a "horror campaign."
